Will AMD Phenom II X4 965 BE edition overclocked to 4.0 GHz bottleneck a EVGA GTX 760 4GB

Will AMD Phenom II X4 965 BE edition overclocked to 4.0 GHz bottleneck a EVGA GTX 760 4GB?

Here are my rig specs:
8GB 1600MHz A-data XPG RAM
( current GPU is GTX 650 OC edition 2GB ) GPU I'm looking to buy is GTX 760 4GB
AMD Phenom II X4 965 BE edition overclocked to 4.0 GHz
MSI 760GM-P23 Mainboard ( Crap mainboard I know...)
1 TB HDD
550 WATT continuous power Roswell power supply. ( will this be enough? or should I upgrade this too? )

Any thoughts?

Should be fine the 760 is a lower power card, but since u have the x4 and if u have had it stable at 4ghz on the board try it out, but if u dont have the OC then dont push that board, like at all lol it shouldnt have a terrible bottleneck on the gpu if at all OC and stock will maybe drop a few fps, should still at the worst play like ur 650 gtx but am not sure on exacts

If you can get it stable on that board it will be in the clear.
Got mine at 4GHz and had no issue, went to 4.2 to get even more clearance for CPU heavy games.

I got it to 4.0 GHz but the motherboard has a messed up throttling sensor issue where it registers that the temp. is 255C and throttles it for a few seconds.
That only happens when CPU is being used like 95% though.

You can disable the bios cpu readout as it seems to be a faulty sensor when OC'd if u know temps will be safe during use. At 4Ghz it shouldnt have a problem running a 4gb 760gtx, my old 3.7Ghz x6 ran my 7970 no prob, thats a lower clock with more cores but not every game was core optimized
